Abstract
Improved process for manufacturing an explosive eutectic composition comprising about 46% by weight ammonium nitrate, about 46% by weight ethylene diamine dinatrate, and about 8% by weight potassium nitrate. First, potassium hydroxide, ammonia, water, nitric acid, and ethylene diamine are reacted in aqueous solution to produce the indicated components of the eutectic mixture. Then the solution is cooled to supersaturate each solute thereof and passed through a continuous crystallizer to crystallize the components of the product in eutectic proportions. The product is then separated from the mother liquor, which is recycled. The process can be operated continuously and safely without producing by-products or employing solvents which must be evaporated from the composition or disposed of.
